We investigated the affect of different feeding strategy on indicators of masticatory apparatus mustelids such as muscle force and bite force, which are determined using the dry skull method. The highest values of muscle forces and bite forces is in species that crack solid food (sea otters, wolverines). In mustelids value of masseter muscle relative to the temporalis increases with the transition to the omnivorous. Temporal muscle is strongly developed among the real predators. The maximum bite force also has the greatest value in large mustelids.
